Cities: Skylines Announced

Paradox Interactive announces Cities: Skylines, an urban planning simulation in
development at Colossal Order (Cities in Motion) for release next year
for Windows, Linux, and OS X. They debuted the project at Gamescom with
this reveal trailer,
and there are also some screenshots on the game's newly minted
official website.
Here's the deal:

Paradox and Colossal Order invite players to create the
cities of their dreams in Cities: Skylines, a massive city simulator from the
creators of the Cities in Motion series. Vast backdrops and maps provide players
with countless ways to improve and expand their cities, building from humble
beginnings up to beautiful, cloud-hugging structures and unique architectural
marvels.

Cities: Skylines will Feature:

Designed to Impress: Massive map sizes and deep,
detailed design controls allow players to construct the cities of their
dreams, running everything from road building and zoning to public services
and taxation – and, yes, public transportation

Policy and Progress: Set a series of civic
policies to guide the city’s growth; fine-tune the placement and direction
of local districts

Local Beautification: Admire the vastness of your
city in a polished visual style and manage a living, breathing city, all the
way down to realistic water flow in the irrigation systems

The Sky is Not the Limit: Strive to build up a
city towards jaw-dropping endgame “wonders,” and then go beyond what is
possible with built-in game modding tools
